Description

Technical Field

[0001] This application relates to the field of steel structure technology, and in particular to a connection structure between a multi-cavity steel plate composite shear wall and a floor slab. Background Technology

[0002] The conventional method for connecting floor slabs and steel plate composite shear walls is to place the floor slab on a T-shaped shear member, and to open support reinforcement holes in the steel plate composite shear wall so that the support reinforcement passes through the steel plate composite shear wall and is anchored into the floor slab.

[0003] Existing connection structures cannot provide waterproofing and reinforcement for shear walls and floor slabs after connection, which leads to rainwater easily penetrating to the connection point and contacting the connectors, causing them to rust and eventually rot, affecting the stability of the connection. To address this issue, this application proposes a connection structure for multi-cavity steel plate composite shear walls and floor slabs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a connection structure between a multi-cavity steel plate composite shear wall and a floor slab, overcoming the deficiencies of existing technologies and aiming to solve the problems in the background technology.

[0005] To achieve the above objectives, this application adopts the following technical solution: a connection structure between a multi-cavity steel plate composite shear wall and a floor slab, comprising a composite shear wall and a floor slab body. The floor slab body is installed on the outer wall of the composite shear wall. A steel plate is installed on the outer side of the composite shear wall. An insert plate is fixed on the outer side of the steel plate and inserted into the inner wall of the composite shear wall. A side plate is fixedly installed on the outer side of the steel plate. A square groove is formed on the inner wall of the side plate. A butt plate is fixedly installed at the bottom of the floor slab body. A water-stop steel plate is installed on the outer wall of the composite shear wall and the top of the floor slab body. Multiple reinforcing bars are installed on the top of the floor slab body.

[0006] In a preferred embodiment, the inner wall of the steel plate is threaded with a stud, and the stud extends threadedly to the inner wall of the combined shear wall, and the outer edge of the stud is threaded with a nut.

[0007] By adopting the above technical solution, steel plates can be stably installed on the outer wall of the composite shear wall, thereby withstanding the pressure of the floor slab and ensuring that it will not easily shake or break under gravity, thus improving the stability of the connection between the steel plate and the composite shear wall.

[0008] In a preferred embodiment, the mating plate is adapted to be inserted into the inner wall of the square groove, and the inner wall of the side plate is threadedly connected to a threaded rod. The outer edge of the threaded rod is threadedly connected to a nut, and the nut abuts against the outer wall of the side plate.

[0009] By adopting the above technical solution, the connecting plate can be stably positioned on the inner wall of the square groove using nut two, thereby ensuring that the floor slab body will not swing laterally after being installed at the top position of the steel plate.

[0010] In a preferred embodiment, the outer side of the waterstop steel plate is threaded with three bolts, and the three bolts are respectively threaded to the inner walls of the combined shear wall and the floor slab body.

[0011] By adopting the above technical solution, the water-stop steel plate can be firmly connected to the composite shear wall and the floor slab using bolts, thereby sealing the connection between the composite shear wall and the floor slab and ensuring that rainwater does not seep into the gap between the composite shear wall and the floor slab, thus improving the waterproofing effect.

[0012] In a preferred embodiment, a plurality of supports are fixedly installed on the top of the floor slab body, the reinforcing bars are disposed on the inner wall of the supports, a positioning ring is installed on the outer edge of the reinforcing bars, and the bottom of the positioning ring is fixedly connected to the top of the floor slab body.

[0013] By adopting the above technical solution, the reinforcing bars can be positioned from the top and bottom using supports and positioning rings, thereby ensuring that the reinforcing bars can be stably set on the top of the floor slab, ensuring that the reinforcing bars will not easily shift their position when the concrete layer is laid, and ensuring the stability and uniformity of the reinforcing bars.

[0014] In a preferred embodiment, a concrete layer is laid on top of the floor slab body, and the reinforcing bars and water-stop steel plates are both located inside the concrete layer at the top position of the floor slab body.

[0015] By adopting the above technical solution, the concrete layer can cover the steel bars and water-stop steel plate on top of the floor slab, thereby ensuring the firmness of the connection between the concrete layer and the floor slab and preventing it from easily breaking.

[0016] In a preferred embodiment, the outer edges of the stud, nut one, threaded rod and nut two are all coated with a galvanized layer.

[0017] By adopting the above technical solutions, it is ensured that it will not be easily corroded, thus guaranteeing its service life and durability, and further ensuring the stability of the combined shear wall and the floor slab after connection.

[0018] The beneficial effects of this application are:

[0019] This multi-cavity steel plate composite shear wall and floor slab connection structure can seal the connection between the composite shear wall and the floor slab by setting a water-stop steel plate, ensuring that rainwater will not seep into the gap between the composite shear wall and the floor slab, thus improving the waterproof effect. In addition, the concrete layer can stably cover the steel bars and water-stop steel plate on the top of the floor slab, increasing its strength.

[0020] This multi-cavity steel plate composite shear wall and floor slab connection structure, by inserting the butt plate into the inner wall of the square channel, can then thread the threaded rod to the inner wall of the side plate and the butt plate, so as to stably position the butt plate in the inner wall of the square channel, which can ensure that the floor slab body will not shift laterally after installation, and improve the stability of the floor slab body when installed on the outer wall of the composite shear wall.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Reference Figure 1-5A connection structure between a multi-cavity steel plate composite shear wall and a floor slab includes a composite shear wall 1 and a floor slab body 2. The floor slab body 2 is installed on the outer wall of the composite shear wall 1. A steel plate 3 is installed on the outer side of the composite shear wall 1. An insert plate 4 is fixed on the outer side of the steel plate 3 and is inserted into the inner wall of the composite shear wall 1. A side plate 7 is fixedly installed on the outer side of the steel plate 3. A square groove 8 is opened on the inner wall of the side plate 7. A butt plate 9 is fixedly installed at the bottom of the floor slab body 2. A water-stop steel plate 12 is installed on the outer wall of the composite shear wall 1 and the top of the floor slab body 2. Multiple reinforcing bars 14 are installed on the top of the floor slab body 2.

[0029] See Figure 2 and Figure 4 The inner wall of the steel plate 3 is threaded with a stud 5, and the stud 5 extends to the inner wall of the combined shear wall 1. The outer edge of the stud 5 is threaded with a nut 6, which allows the steel plate 3 to be stably installed on the outer wall of the combined shear wall 1, thereby withstanding the pressure of the floor slab body 2, ensuring that it will not easily shake or break under gravity, and improving the stability of the connection between the steel plate 3 and the combined shear wall 1.

[0030] See Figure 4 and Figure 5 The mating plate 9 is adapted to be inserted into the inner wall of the square groove 8. The inner wall of the side plate 7 is threaded with a threaded rod 10, and the outer edge of the threaded rod 10 is threaded with a nut 11. The nut 11 abuts against the outer wall of the side plate 7, so that the mating plate 9 can be stably positioned on the inner wall of the square groove 8 by using the nut 11. This ensures that the floor slab body 2 will not swing laterally after being installed at the top position of the steel plate 3.

[0031] See Figure 2 The outer side of the waterstop steel plate 12 is threaded with three bolts 13, which are respectively threaded to the inner walls of the combined shear wall 1 and the floor slab body 2. This allows the waterstop steel plate 12 to be securely connected to the combined shear wall 1 and the floor slab body 2 using the bolts 13, thereby sealing the connection between the combined shear wall 1 and the floor slab body 2 and preventing rainwater from seeping into the gap between the combined shear wall 1 and the floor slab body 2, thus improving the waterproofing effect.

[0032] See Figure 2 Multiple supports 15 are fixedly installed on the top of the floor slab body 2. The reinforcing bars 14 are set on the inner wall of the supports 15. The outer edge of the reinforcing bars 14 is equipped with positioning rings 16. The bottom of the positioning rings 16 is fixedly connected to the top of the floor slab body 2, so that the reinforcing bars 14 can be positioned from the top and bottom sides using the supports 15 and positioning rings 16. This ensures that the reinforcing bars 14 can be stably set on the top of the floor slab body 2, and ensures that the reinforcing bars 14 will not easily shift their position when the concrete layer 17 is laid, thus ensuring the stability and uniformity of the distribution of the reinforcing bars 14.

[0033] See Figure 1 and Figure 2 A concrete layer 17 is laid on the top of the floor slab body 2. The reinforcing bars 14 and the water-stop steel plate 12 are all located inside the concrete layer 17 at the top position of the floor slab body 2. This allows the concrete layer 17 to cover the reinforcing bars 14 and the water-stop steel plate 12 on the top of the floor slab body 2, thereby ensuring the firmness of the connection between the concrete layer 17 and the floor slab body 2 and preventing it from easily breaking.

[0034] See Figure 1 , Figure 2 and Figure 5 The outer edges of studs 5, nuts 6, threaded rods 10 and nuts 11 are all coated with a galvanized layer, which ensures that they will not be easily corroded, thus guaranteeing their service life and durability, and further ensuring the stability of the combined shear wall 1 and the floor slab body 2 after connection.

[0035] Working principle: When using this device, first take the steel plate 3 and insert the insert plate 4 into the inner wall of the combined shear wall 1. Then, the studs 5 can be threaded to the steel plate 3 and the inner wall of the combined shear wall 1 respectively, to firmly connect the steel plate 3 and the combined shear wall 1. At the same time, the nut 6 can be threaded to the outer edge of the stud 5 to lock the stud 5. The floor slab body 2 can be installed on the top of the steel plate 3. At the same time, the mating plate 9 is inserted into the inner wall of the square groove 8. Then, the threaded rod 10 can be threaded to... The inner walls of the side plate 7 and the butt plate 9 are connected to the square groove 8 to stably position the butt plate 9 on the inner wall of the square groove 8, ensuring that the floor slab body 2 will not shift laterally after installation. At the same time, the water-stop steel plate 12 can be stably installed on the outside of the combined shear wall 1 and the top of the floor slab body 2 using bolts 13. Then, the steel bar 14 is positioned on the top of the floor slab body 2 using the support 15 and the positioning ring 16. Finally, a concrete layer 17 is laid on the top of the floor slab body 2 to cover the steel bar 14 and the water-stop steel plate 12.
